This is probably a dumb question, but I'm having a hard time finding answers for it. I was nominated a few weeks ago and notified my employers. They want me to start on Monday and I was going to fly out to Halifax tomorrow morning. The problem is, my nomination certificate and letter of support have not yet arrived in the mail. When applying for a work permit at the border, will they only accept the originals of those two documents or will they take copies? Does anyone have any experience with this?
